At COP26, Parties adopted a set of Decisions to underpin and enable international cooperation under Article 6 of the Paris Agreement, including through the use of carbon markets. These Decisions provide a framework for Parties to transfer ‘mitigation outcomes’ generated within their jurisdiction for use by other Parties or entities, or for Parties to use mitigation outcomes generated elsewhere towards their NDC. Following this, Parties adopted further Decisions elaborating on aspects of the framework at COP27, including the central electronic architecture to manage Article 6-related information, templates for national reporting, and the process of reviewing these reports.
